GEORGE A. AMBLER, OF NEWARK, NEW JERSEY.

MAILING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 586,153, dated July 13, 1897. Application filed January 11, 1896. Serial No. 575,109. (No model.)

To (all whom it mm! concern Be it known that I, GEORGE A. AMBLER, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Nailing-Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

This invention relates to improvements in nailing-machines and it consists in the novel arrangements and combinations of the several parts of mechanism hereinafter fully set forth, and finally embodied in the clauses of the claim.

The invention is fully illustrated in the accompanying sheets of drawings, in which- Figure l is a front elevation of a nailingmachine provided with the mechanism embodying the principles of my invention. Fig. 2 is a side view of my novel form of combined feeding device and cutting mechanism, and Fig. 3 is a front view of the same. Fig. 4 is a vertical section of the combined feeding device and cutting mechanism, taken on line as in Fig. 3; and Fig. 5 is a cross-section taken on line in Fig. 4 and looking in the direction of arrow Fig. 6 is a bottom view of the feeding device. Fig. 6 is a cross-section taken on line it u in Fig. 6. Fig. 7 is a face view of the cutting or trimming mechanism represented in said Fig. 2, and Figs. 8 and 9 are perspective views of the different forms of gage-rollers adapted to be used in connection with the cutting mechanism. Fig. 10 is a side view of a portion of the standard of a nailing-machine and a modified form of construction of jack or standard on which the last and shoe to be nailed are supported.

Similar letters'of reference are employed in all the abovedescribed views to indicate corresponding parts.

In said drawings, A represents one of the Well known constructions of nailing machines, comprising therein a suitable stand ard a, to which is secured a frame a of proper shape to support the various working parts of the machine, said frame being provided formed, as clearly shown in Fig. 4.

with suitable bearings a and a for the main shaft or spindle (1., provided with a loose pulley a for receiving the driving-belt.

The several parts of the structure represented in Fig. 1, which are old, per 86, are the wire-reel b, and the nailing device, of which I) is the driver-bar, and b are parts of the mechanism for operating a device for severing the wire to form the nail.

Pivotally connected with the lower portion of the standard a, as at a, is a foot-lever d, having a weight d adj ustably arranged thereon, and d is a rod which is operatively attached to a foot-lever (Z and is connected with a clutch-collar a on the shaft a for operatively connecting said loose pulley a with the shaft a, and thereby drive the several parts of the nailing-machine. Pivotally attached, as at (1 to said lever cl is a rod (1, usually called the jack, which is held in the left hand of the operator of the machine and is provided at the top with a short post or pivot 61 for the reception of the ordinary last on which the parts of the shoe are arranged, and can be brought directly into proper position beneath the novel form of feeding device when the soles are to be united to the upper of the boot or shoe or directly in front of the cuttingtool of the trimmingoff mechanism to cut down the projecting edges of the sole and trim it off properly.

The construction of said feeding device is clearly illustrated in Figs. 2, 3, 4, 5, and 6, and consists, essentially, of a suitable plate or block 0, secured by means of screws or rivets a (see Fig. 6) to the portion a of the nailing-machine A in such a manner that the forward edge of said plate or block a is located directly behind a tubular post a, which is secured in said portion a in the manner substantially as illustrated in Fig. 4, and through which post the nail or wire is forced by the driver-bar b in the usual manner. Said block or plate 0 is cut away or grooved out, as at c and c and is provided with a longitudinally -arranged hole 0 forming a bearing for the portion 0 of a spindle or shaft Said portion 0 is preferably of a smaller diameter than the main portion of the spindle, whereby an offset or shoulder is Onthe free end of said portion 0 of the spindle c is a pinion c ,which, with the shoulder on said spindle, retains the same in its rotative position in the hole 0 in said plate or block 0, as will be clearly evident from an inspection of Fig. 4:. On the opposite end of said spindle c I have secured, preferably by means of a set-screw 0 a suitable driving-wheel 0 over which I pass a belt a which in turn is arranged over a pulley a on the main driving shaft or spindle a of the machine A, as clearly represented in Fig. 1. In this manner the spindle c rotates the pinion 0 as will be understood. Rotatively arranged in bearing portions 0 in said plate or block 0 and in perforations or holes in a bracket f, secured by means of screws f orin any other well-known manner to the end of the portion a of the machine A, are a pair of short spindles f each of which is provided with a gear-wheelf meshing with the pinion 0 arranged in the cut-away portion 0 of the block 0, and with suitably corrugated or serrated feed-rollers f substantially as illustrated in Fig. From the arrangement of said pinion c and the two gear-wheels f it will be evident that the short spindles and hence the feed-rollers f thereon will both turn in the same direction during the operation of the machine. Thus it will be evident that when the shoe on the jack has the edge of the outer sole placed beneath the feed-rollers f the operator can easily hold the shoe in its position on the jack while the feed-rollers f slowly turn the shoe, and the weight 01 on the rod 01 forces the outer edge of the outer sole of the shoe into frictional contact with the corrugated or serrated surfaces of said feed-rolls f thereby causing the feeding operation, while the nails are driven through the outer sole and into the inner sole of the shoe to unite the several parts of the shoe in the usual and Well-known manner.

In lieu of the construction of jack illustrated in Fig. 1 I may use the form shown in Fig. 10. In this instance the standard CL of the machine A is provided with a pair of brackets c4 having perforated ends, in which I arrange a rod 61 said rod being held in position by means of a collar (1 secured thereon by means of a set-screw d and a coiled spring (1 which takes the place of the weight d on the rod cl and forces the rod 61 pivotally attached, as at (1 upwardly in precisely the same manner as has just been described. Said rod may be provided with a foot-piece (Z for lowering the same when necessary.

If desired, I may use in connection with the several parts of the machine a cutting mechanisn1 for trimming off the surrounding edge of the sole as it is being nailed fast. The construction of said cutting mechanism is clearly illustrated in Figs. 2, 3, 4i, and 7, and consists, essentially, and as will be more clearly understood from an inspection of said Fig- 7, of a suitable bracket 0, having the flanges 6', provided with perforations e Said bracket is provided with a groove 6 which can be fitted. over a correspondingly-arranged rib or projection c on the under side of the plate or block 0 (see Fig. 6) and then secured to said block or plate 0 by means of suitable bolts or screws g, which are screwed into the holes e in said plate 0, as clearly shown in Fig. 2. In a bearing in the lower part of said bracket 6 I have arranged a spindle 6 provided with a grooved wheel 6 which is driven by means of a belt 72, passing over an idler 0, and a suitable pulley-wheel a on the main shaft a of the machine, substantially as illustrated in Fig. 1, but any other suitable means for operating said wheel a may be employed. As will be seen from Figs. 2, 4:, and 7, on one side of said wheel 6 is a projection a which is eccentrically arranged in reference to the central axis of said spindle c and has a ring a loosely but operatively arranged thereon, substantially as shown. Said bracket is also provided with a forwardlyextending projection 6 which is grooved and forms a suitable guide e for the shank t" of the cutting-tool 2'. A plate is secured by means of screws 70 or in any other well-kn own manner over said guide and thereby operatively retains the shank t" of the cutting-to0l in said guide.

The cutting-tool i is connected with the shank '21 in any well-known manner, but preferably by having its end 11 arranged in a socket i in the end of said shank t" and then fastened by means of a set-screw 2' as will be clearly understood. The lower end of the shank t" is adjustably secured by means of a set-screw t to a collar t, having a teat or projection 2' which fits into a hole in said ring 6 on said eccentric projection, as shown in Fig. 4. To the opposite sides of said bracket 6 are secured, by means of screws j or otherwise, the adjustable arms Z and I, each of which has a pivotal post or screw Z on its end and on which are rotatively arranged certain gage-rollers Z which may be formed as illustrated more particularly in Figs. 8 and 9, but they may be of any other suitable configuration, as will be evident. Said gage-rollers Z may be made of any suitable material, such as wood, metal, fiber, 850., but I prefer to use a comparatively soft material, such as rubber or the like.

Vhen the outer surface of the outer sole is brought in contact with the feed-rollers f hereinabove mentioned, said gage-rollers Z act as guides to the operator and prevent the sole or shoe from being arranged improperly beneath the feed-rollers, and all nails to be driven into the sole will be equidistant from the surrounding edge of the sole, whereby a finished job is the result. These guides also serve the same purpose when the cutting mechanism is employed, and the rapidly-reciprocatin g cutter or knife will properly trim the surrounding edge of the outer sole of the shoe, as will be clearly evident.

From the above description it will be seen that an operative device or attachment has been constructed which can be used on nailing-machines of any Well-known construction as a feeding device during the process of joining the soles to the upper of the shoe by means of wire nails, or it may be used solely as a trimmer for cutting down the surrounding edge of the sole of the shoe, or it may be used as a combined feeding and trimming attachment in machines of this class.

In the manufacture of hand-sewed 'shoes my novel form of attachment, hereinabove described, can be used for tacking the outer sole to the shoe and trimming around the seat of the sole, after which the shoe is ready to be finished.

I am fully aware that many changes may be made in the details of construction and the general arrangements of the several parts of mechanism herein set forth without departing from the scope of my invention. Hence I do not limit my invention to the exact arrangements and combinations of parts as herein described and illustrated.
